Interesting idea, Mooman--I have a box full of the Boss Pedals, mostly use just compressor and a touch of delay, and the pedals are alway in the way--

A bit of processing is necessary, because the pick-up and amp change the sound of an acoustic instrument significantly, and often not to the good. The thing I hate is that, after you've figured out what you want to use, you have to practice with your whole set up, because it makes rehearsal more complicated--if you don't, though, your sound can really get messed up--
